Additional information

The movie is about Yan (Tony Leung Chiu Wai) who is a police undercover in the Triads while Ming (Andy Lau) is in the reversal of a triad undercover in the police department. Leading parallel but opposite lives, both feel the tremendous pressure as well as stressfully trapped in their false and increasing dangerous surroundings. Both have been walking on the thin fatal line until on one fateful evening they finally meet each other. On the other hand, both the police and the Triads have knowledge that there's an undercover amongst them and the chase is on as they compete who would 'dig' out their `mole' first.
